IMPROVED DRILL OR WELL TUBE.

Specication forming part of Letters Patent No. 59,608, dated November 13, 1866.

To all 'whom it may concern:

Be it known that I, JOHN HUTerrrNs, of Elmira, in the county of Ohemung, and in the State of New York, have invented acertain new and useful Instrument for Sinking Hydrants; and I do hereby declare that the following' is a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming a part of this specification.

In the drawings, Figure l is a side eleva` tion, and Fig. 2 is a vertical section.

My invention consists in the peculiar construction of an instrument to be used in sinking hydrants, as hereinafter more fully appears.

A represents a hollow cylindro-conical drillpoint made of cast-iron of a size proportioned to the hydrant or pump to be used. For a three-inch hydrant, pump, or well, I make use of a drill-point, A, of a little more than three inches in diameter and about two feet-long, of the shape shown in drawings, or conical from base to point. rIhe point B is for an i-nch or more cast solid, so that it may'not be easily crushed. a a are a number of conical holes or slots through the sides for the admission of the water. These openings, whether circular or of other shape, are made larger inside of the cylinder than at their outer surface, (see Fig. 2,) so that any obstruction which can get from the outside into the hole can escape through the hole intothe tube and thence be discharged. c is a fiat spiral thread winding two or three times around the point. This thread is flattened or planed off, as shown in drawings, so as to leave the thread only at or near the angles where two of the threadplanes meet. In making' the pattern the thread would be left as usual, and then be planed off hexagonally, so that an end view of the thread would disclose a hexagon.

The best and cheapest mode of making the instruments is to cast them of one piece of iron.

In. operating my invention, I rst select a suitable place for the hydrant, and then begin to drive down the drill-point with a sledge. After it is driven below the ground surfacea follower is applied, and that re ceives and transmits the blow. For small bores a sledge will answer; but if the ground be hard, a light pile-driver best answers the purpose. By applying a wrench or lever the drill-point can 4be turned occasionally, so as to act as a screw, and thereby facilitate the operation. When the water is reached the pipes can be put in place resting upon the instrument, which 'is left in the bottom of the hole, and any desired pump can be applied.

I am aware that wells, &c., have been heretofore made by driving tubes into the ground, and hence I do not claim that mode of making wells as new.

I claiml The. hollow conical drill-point A, of castiron, provided with beveled holes or slots a, with the spiral lian ge c, flattened as described, the whole being constructed as described, and for the purposes set forth.

Iutestimony that I claim the abovedescribed invention I have hereunto signed my name this 6th day of July, 1866.

JOHN HUTOHINS.
